"Written by two researchers in the field, this book is a reference to explain the principles and fundamentals in a self-contained, complete and consistent way.

This book is primarily intended for graduate chemists and chemical physicists. Indeed, it is based on a graduate course that I give in the Chemistry Depart ment

In this book, quantum mechanics is developed from the outset on a relativistic basis, using the superposition principle, Lorentz invariance and gauge invariance
